Codes
|
The Library of Congress (LC), National Library
of Medicine (NLM), the British Library (BL), National Library of
Canada (NLC), National Library of Australia (NLA) and National Serials
Data Program (NSDP) use blank and numeric codes. Libraries
participating in the Program for Cooperative Cataloging use blank and numeric
codes when entering BIBCO or CONSER records (i.e., those containing
an authentication code in field 042). All other OCLC participants
cataloging online enter records at I for Full-level, 4 for
Core-level and K for Minimal-level.
The following list identifies and defines the types of
codes found in WorldCat records that are entered through online
input or through a batch process. For more information on input
of Full-, Core-, Minimal- and Abbreviated-level cataloging, see
section 2.4, "Full,
Core, Minimal and Abbreviated-Level Cataloging."
|
|
|
Full-level. The most complete MARC record. The
record's information is derived from a physical inspection of
the item. Code blank is used by authorized national
bibliographic agencies and libraries participating in PCC (BIBCO
and CONSER). BIBCO and CONSER records will contain an authentication
code in field 042.
All other OCLC participants cataloging online at Full-level,
use I.
|
|
|
1 |
Full-level, material not examined. The next-most-complete MARC record after
the Full-level. The record's information is derived from
an existing description of the material (e.g., a printed catalog
card). All the information as found on the existing description
is input. The physical item is not reinspected.
Code 1 is used primarily in the
retrospective conversion of records.
|
|
|
2 |
Less-than-full level, material not examined. A record between Minimal-level and Full-level
cataloging. The record's information is derived from an
existing description of the material (e.g., a printed catalog card).
The physical item is not reinspected. All of the
descriptive access points are transcribed. The authoritative headings
may not be current. Code 2 is
used, for example, when only a subset of data elements is transcribed
from a catalog card during a retrospective conversion to the MARC
format.
Code 2 is used only by the Library
of Congress.
|
|
|
3 |
Abbreviated level. A brief record that does not meet Minimal-level
cataloging specifications. Headings in the record may reflect established
forms to the extent that such forms are available at the time the
record was created.
Code 3 is used for defined projects.
|
|
|
4 |
Core-level. A
record that is less-than-full, but greater-than-minimal-level cataloging
and that meets core record standards for completeness. Any OCLC participant
may enter a Core-level record as long as Core-level input standards are
followed. A Core-level record that is entered by a library participating
in PCC through BIBCO or CONSER will contain an authentication code
in field 042. |
|
|
5 |
Partial (preliminary) level. A record in process. Such a record is not final.
You cannot make assumptions about the status of the headings or
the descriptive cataloging level. |
|
|
7 |
Minimal-level. A record that meets the National Level Bibliographic
Record specifications. The creating agency considers
such a record final. Headings are checked against an authority file
and reflect established forms to the extent that such forms are
available at the time the Minimal-level record was created.
OCLC participants cataloging online at Minimal-level,
use K.
|
|
|
8 |
Prepublication level. A prepublication-level record. This includes a record created
through the Cataloging-in-Publication (CIP) program and the National Serials
Data Program. |
|
|
I |
Full-level input by OCLC participants. A record that conforms to OCLC's level I input
standard. The level I input standard represents
full cataloging. Use level I when transcribing
LC or NLM copy. |
|
|
K |
Less-than-full input by OCLC participants. A record that conforms to OCLC's
level K input standard. The level K input
standard represents less-than-full cataloging. |
|
|
L |
Full-level input added from a batch
process. A full-level record batchloaded from
an institution other than LC, NLM, BL, NLC or NLA. |
|
|
M |
Less-than-full added from a batch process. A less-than-full record batchloaded from
institutions other than LC, NLM, BL, NLC or NLA. |
|
|
E |
System-identified MARC error in batchloaded
record. The system assigns code E to
indicate that a machine-detected MARC error(s) was found in the bibliographic
record during the batchloading. These system-detected errors are often
obvious (e.g., an illegal tag, invalid subfield codes, etc.). Use E-level records
to Produce cards or Update holdings. However, you cannot change
code E. Before using an E-level
record, correct any errors apparent in the record. OCLC reviews
and corrects these records. Corrected records have the appropriate ELvl. |
|
|
J |
Deleted record. The record has been deleted by the institution which
created it. The code is used only for special cases of batchloaded
records for selected files, such as national libraries (LC, NLM,
BL, etc.) and some files loaded as resources for cataloging (NetFirst,
Puvill, etc.) |
